Unified mobile security system and method of operation

ABSTRACT

A mobile secure agent on a wireless device executes one or more authenticated data collection profiles provisioned by a private profile producer. Each data package can only be transmitted to a collector certificated by the same private profile producer. Update profiles are signed and provisioned through a tunnel initiated from the mobile secure agent. A Certificate Authority provides libraries, anchors, and certificates in a key management message module to each mobile secure agent which enables revocation and replacement of certificates. Data stored in this way on a wireless device may only be transmitted in encrypted form to an authenticated destination.

This application is a divisional application of, and claims priority to each of, U.S. patent application Ser. No. 16/803,036, filed Feb. 27, 2020, which is a continuation application of U.S. patent application Ser. No. 15/980,504, filed May 15, 2018, and issued as U.S. Pat. No. 10,616,208 on Apr. 7, 2020, which is a divisional application of U.S. patent application Ser. No. 13/726,580, filed Dec. 25, 2012, and issued as U.S. Pat. No. 9,973,492 on May 15, 2018. The foregoing priority applications are hereby incorporated by reference herein in their respective entireties.

BACKGROUND

Conventional mobile wireless devices may be configured to collect quality of service statistics or under conditions collect and transmit data defined in a data collection profile and executed by an agent. User expectations of a sense of connectedness, and cradle to grave support services are potentially in conflict with a desire for privacy.

Thus, it can be appreciated that what is needed is a way to securely collect and transmit private data exclusively to authorized recipients and to protect users from data leaks to unauthorized recipients and verify the provenance of data collection profiles prior to installation and execution at any mobile device.

BRIEF DESCRIPTION OF DRAWINGS

To further clarify the above and other advantages and features of the present embodiments, a more particular description of the embodiments will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It is appreciated that these drawings depict only typical embodiments of the application and are therefore not to be considered limiting of its scope. The application will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:

FIGS. 1-4 are block diagrams of embodiments of the system; and

FIGS. 5-6 are flowcharts of method steps of a processor controlled as an aspect of the embodiments of the application.

SUMMARY

A system comprises a plurality of mobile secure agents each of which has received from a certificate authority a plurality of anchors, certificates, libraries, and related authentication modules. Upon determining conditions specified in at least one data collection profile, a mobile secure agent will transmit an encrypted data package to at least one certified data package collector. No transmission can occur to a collector without a certificate signed by a specific signing authority. Each of the private profile producers provides a certificate to a data package collector which has been authenticated by the unified mobile security certificate authority (CA). Each private profile producer validates an initial or updated data collection profile stored at a certified profile update provisioner. The update provisioner is enabled to establish a certificated SSL tunnel upon request from a mobile secure agent.

Each mobile secure agent requests a certificated SSL tunnel on its own schedule, on conditions encoded in a profile, or in response to a Black Short Message System (BSMS) transmission. Upon request from a private profile producer, a secure notifier will transmit a black short message system notification to at least one mobile secure agent that a new profile may be retrieved or that the data package collectors are ready for an upload, or that other key management messages are pending delivery.

Each private profile producer enables a data package collector to receive only data packages collected according to an authenticated profile signed by the private profile producer. The profiles are retrieved by the mobile secure agents through an SSL tunnel. A Certificate Authority can revoke or initialize new certificates for each private profile producer.

DETAILED DISCLOSURE OF EMBODIMENTS

Reference will now be made to the drawings to describe various aspects of exemplary embodiments of the application. It should be understood that the drawings are diagrammatic and schematic representations of such exemplary embodiments and, accordingly, are not limiting of the scope of the present application, nor are the drawings necessarily drawn to scale.

Referring now to FIG. 1, a system embodiment 100 has at least one of a plurality of mobile secure agents 110 installed in a mobile device which comprises a baseband processor, an application processor, display, and memory. The mobile secure agent comprises a Key Management Message Module 199 a combination of hardware and software which is provided by and signed by a unified mobile security certificate authority (CA) 900 in an embodiment a self-signed certificate authority. The CA has also authenticated at least one private profile producer 811. The mobile secure agent also has an authenticated profile 111 which has its own certificate and which can be validated or revoked by the Key Management Message Module 199. Upon discovery and evaluation of a set of conditions contained within the profile, the processor enables the mobile secure agent to collect data and to transmit data packages. Collected data may be discarded if the transmission conditions are never fulfilled. A data package may be encrypted and may be transmitted only to a certified data package collector 211 which has a corresponding key to receive the package and, in an embodiment, to decrypt the package. The data package may be encrypted only during transit or may be encrypted for storage. Thus, the data package can only be transmitted to a package collector having the correct certificate and the encrypted data can only be decrypted by a collector having a key corresponding to the authenticated profile. Furthermore, the data is collected and subsequently transmitted according to a profile authenticated by the Key Management Message Module 199 which comprises libraries, anchors, certificates, and executable code.

Referring now to FIG. 2, a private profile producer 820 is authenticated by the unified mobile security certificate authority (CA) 900 and generates an authenticated profile which is distributed by a certified profile update provisioner 400. A provision is initiated by a mobile secure agent 120 by launching a certificated SSL tunnel 500. The mobile secure agent 120 also comprises a provisioning authentication element 125 which starts the SSL tunnel, requests an updated profile, and authenticates the received profile 122 using the Key Management Message Module 199. All profiles are requested by the mobile secure agent from a certificated profile update provisioner and validated using the Key Management Message Module 199 provided by the CA 900. An aspect of the application is the direction of this transfer which is initiated from the mobile device.

Referring now to FIG. 3, in an embodiment, a private profile producer 830 authenticated by the CA 900 may request a notification transmission by a secure notifier 700 which transmits a black short message system (BSMS) message 630 to a selected mobile secure agent 130. The notification is also authenticated by a notification authentication module 136. The notification can only trigger pre-defined operations at the mobile secure agent 130. In one embodiment, the notification causes the provisioning module to request an update profile from the profile provisioner. In an embodiment, the notification can alert the profile that a data package collector is available or reschedule a transmission of a data package. In an embodiment, the notification can initiate a request for an update to the Key Management Message Module. The Key Management Message may revoke a certificate and cause the Key Management Message Module 199 to advance to a new authentication anchor, thereby creating a new basis for authentications. As illustrated in FIG. 3, all the sessions which transmit payload are initiated by and from the Mobile Secure Agents to servers. The Short Message System provides triggers but cannot control the Mobile Secure Agents. We refer to a Black Short Message System to indicate that the SMS messages for notifications are not intended for display to the user of the mobile device.

Referring now to FIG. 4, each of a plurality of private profile producers 810-890 submit new profiles for authentication by the CA which provides them to the profile update provisioner 400. The private profile producer may select a set of mobile secure agents to be notified to request the updated profile by the secure notifier 700. Each of the selected mobile secure agents 110-190 which are notified requests an updated profile by initiating an SSL tunnel 500, receiving and validating a new profile using the Key Management Message Module 199. Each data collection and transmission profile specifies conditions to collect certain data at the selected mobile device and other conditions to transmit the data packages to a certain certified data package collector. In a first embodiment, the data packages are encrypted prior to transmission and stored in encrypted form. In a second embodiment, the data packages are encrypted during transit but decrypted upon receipt at the collector. Certificates at the data package collectors prevent data packages from being misrouted to unauthorized receivers.

Referring now to FIG. 5, an exemplary method for operation of a mobile secure agent comprises, upon completing conditional collection of data according to a data collection profile and determining conditions for transmitting a data packages are fulfilled, initiating a secure connection to a certified data package collector server as specified within a profile 101, in an embodiment an HTTPS protocol known in the art, authenticating the data package collector server is certificated by the unified mobile security certificate authority (CA) 103, and transmitting the data package 105. In an embodiment, encrypting the data package 104 using a key provided in the Key Management Message Module. In an embodiment, the method further includes updating a profile: upon determining that it is necessary to update a data collection profile (either according to the extant data collection profile or according to a notification described below), initiating a secure connection by the mobile secure agent to a certified profile update provisioner server 201, authenticating the profile update provisioner server has a certificate signed by the unified mobile security certificate authority (CA) 203, requesting a profile update 205, authenticating the received profile update using the Key Management Message Module 207, and installing the new profile update 209. In an embodiment, the method further comprises receiving a black short message system (SMS) message 301 from a secure notifier, authenticating the black SMS message 303 using the Key Management Message Module, and opening at least one secure connection 305 from the mobile secure agent to obtain a profile update, a Key Management Message, or to transmit a data package to a data package collection server.

It can be appreciated that the benefit of the disclosed security architecture provided by the subject matter of this application enables certificates to be revoked and replaced. Data collected for one private profile producer cannot be received or decrypted by another private profile producer. Profiles are authenticated before use. Profiles are retrieved from a certificated profile update provisioner by the mobile secure agent and cannot be pushed to the mobile secure agent. Each notification can be authenticated and ignored if not authenticated. This provides a system where only private profile producers trusted by the end user of the wireless mobile device may cause data to be collected and then under certain conditions transmitted to a data package collector authenticated by the profile. No data is collected and stored at the mobile secure agent unless a profile has been authenticated by the Key Management Message Module 199.

Referring now to FIG. 6, a method for operating a unified mobile security system comprises receiving a profile from a private profile producer 401, signing the profile as the unified mobile security certificate authority (CA) 403, storing the signed profile at a profile update provisioner server 405, providing the profile update provisioner server with a certificate signed by the unified mobile security CA 407, providing a certified data package collector with a certificate from the private profile producer signed by the unified mobile security CA 409, signing a black short message system (SMS) message by the unified mobile security CA 411 and transmitting it to selected mobile secure agents 413, receiving connection requests from a mobile secure agent 415, receiving data packages 417, responding to a request for a profile update 419, and responding to a request for an updated Key Management Message 421.

Other aspects of the application are methods for operation of the mobile agent in control of a processor, methods for operation of a server to provision profiles, generate profiles, sign profiles and certificates, and provide key management modules. These methods and apparatuses are in embodiments:

A method for operating a mobile secure agent controlling a processor on a wireless mobile device, upon a condition in a profile evaluating as true, opening a secure SSL tunnel to a data package collector server using a certificate associated with the profile; encrypting a data package as specified in the profile; and transmitting the encrypted data package to the specified data package collector server having the associated certificate.

In another embodiment, the method further comprises upon receiving a black short message system notification and authenticating a signature associated with the notification, opening a secure SSL tunnel to a profile provisioning server using a certificate; requesting any updated profile; and authenticating the updated profile upon reception.

In another embodiment, the method further comprises upon receiving a request for a data package transmission in a notification, and authenticating the signature associated with the notification, opening a secure SSL tunnel to a data package collector server using a certificate; encrypting a data package as specified in a profile; and transmitting the encrypted data package to the specified data package collector server having a certificate.

Another aspect of the application is at a unified mobile security certificate authority apparatus, a method comprising: generating a plurality of trust anchors; receiving a plurality of certificates from private signing authorities and authenticating each one; and provisioning a plurality of mobile secure agents with trust anchors, cryptographic libraries, default profiles, and at least one signed certificate.

At a private profile producer apparatus, an embodiment controls one or more processors to perform a method comprising: generating a certificate for authentication by a unified mobile security certificate authority; provisioning a data package collector with an authenticated certificate; distributing a certified profile update to a provisioner server; and directing a secure notifier apparatus to transmit a black short message system notification to a plurality of mobile secure agents to request an updated profile from the provisioner server. A conventional short message system which does not display certain messages to the user can be understood as a black short message system for notification.

Another aspect of the application is a system communicatively coupled together by a network comprising: a secure notifier apparatus configured to receive a direction from a private signing authority and as a result, transmit a black short message system to at least one mobile secure agent controlling a processor on a wireless mobile device; a certified profile update provisioner server configured to receive a certificate and an updated profile, receive a request for an SSL tunnel, authenticate the tunnel request using the certificate, and transmit a certified profile to a mobile secure agent; a certified data package collector configured to receive a certificate from a private signing authority, receive a request from a mobile secure agent for a secure channel, authenticate using the certificate, and receive encrypted data packages for storage.

In an embodiment, the system further has at least one private profile producer apparatus, communicatively coupled to a unified mobile security certificate authority apparatus, and further coupled to the secure notifier apparatus, the certified profile update provisioner server and to a certified data package collector server.

In an embodiment, the system further includes the unified mobile security certificate authority apparatus coupled to a plurality of mobile secure agents configured with cryptographic libraries, default profiles, a plurality of authentication anchors and at least one certificate.

For expository clarity and illustrative simplicity separate connections are shown and described. However, as known to those skilled in the art, a single apparatus comprising a processor and memory can serve one or more of the disclosed functions. As an example, the profile provisioner server and the data collector servers may in an embodiment be virtual machines within a single apparatus. In an embodiment the separately shown secure connections initiated from the mobile secure agents may be all uses of a single protocol. In an embodiment, the one or more private profile producers may share occupancy of an apparatus together and in combination with the unified mobile security certificate authority as long as they do not have direct connection to the mobile secure agents. Similarly, the secure notifier can be a conventional SMS apparatus but having the limitation of not providing messages visible to the user of the mobile device and including an authentication code within or associated with the message or series of messages.

CONCLUSION

The present embodiment is easily distinguished from non-unified security architectures which only provide piece-meal security solutions to mobile devices such as tablets, and smart phones. The present embodiment is easily distinguished from conventional security systems by its unified mobile security certificate authority. It can be appreciated that conventional wired network certificates are too voluminous for efficient use in a mobile wireless network. It is distinguishing characteristic that profiles and Key Management Messages and Modules are not “pushed” to mobile devices which would create an opportunity for unauthorized data leaks.
